Needle roller bearings are rotational motion bearings in which a
thin needle-shaped roller is incorporated into a rolling element.
They have a low cross-section height and high load capacity
compared with ball bearings. Being small, needle roller bearings
contribute to reducing overall machine size, and are thus widely
used in various applications such as automobiles, motorcycles,
printing presses, industrial robots and construction equipment.

Features of hk needle bearing

HK is a one way needle clutch which applied flexibly of the
technology of

small bearings ,and

make the structure more compact as well as higher performance.

Material of hk needle bearing

Outer ring: is made by sintered metal

Spring: is made by stainless steel

Needle roller bearing

A needle roller bearing is a bearing which uses small cylindrical
rollers.

They are used to reduce friction of a rotating surface.Needle bearings have a large surface area that is in contact with
the bearing outer surfaces compared to ball bearings. Additionally
there is less added clearance (difference between the diameter of
the shaft and the diameter of the bearing) so they are much more
compact.

The typical structure consists of a needle cage which orients and
contains the needle rollers, the needle rollers themselves, and an
outer race (sometimes the housing itself).Radial needle bearings are cylindrical and use rollers parallel to
the axis of the shaft. Thrust needle bearings are flat and use a
radial pattern of needles.Full complement bearings have solid inner and outer rings and
rib-guided cylindrical rollers. Since these bearings have the
largest possible number of rolling elements, they have extremely
high radial load carrying capacity and are suitable for
particularly compact designs.
